I claim and desire to secure by Letters Patent of the United States the followingz 1. A baking utensil of the class described comprising a circular Wall section having an opening formed in its bottom, a curl arranged at the lower edge thereof, a beaded removable bottom resting upon said curl, said bottom having a core arranged centrally thereon, and a resilient element connecting said core to said bottom whereby said core may be detached from the bottom.

2. A baking utensilv of the class described, embodying a circular open wall section havingA an inturned curl formed at its lower edge, a beaded bottom section adapted to rest in said curl, said bottom having a centrally disposed core arranged thereon, and means for detachably securing said core thereon comprising a spring pressed element adapted to cause the separation of said bottom and said core at will by the operator.

3. In a baking utensil of the class described, a circular open wallA section having a removable bottom arranged therein, a cylindrical core arranged on said bottom, a. bottom arranged in said core, a slot formed in the core bottom, and a spring pressed rivet arranged in the pan bottom and adapted to register and non-register with said slot when said core is turned relative to said pan bottom.

4. In a baking utensil of the class described, a wall section and a removable bottom therefor, a cylindrical core arranged on said bottom and itself vhaving a bottom section, said core bottom having a slot arranged therein, a retaining rivet extending through the pan bottom and adapted to register with said slot and when turned relative to the slot adapted to fasten the core to said pan bottom, and a nat retaining spring arranged on said rivet and adapted to hold the core and pan bottom in xed relation.
